Subject
At its 11th meeting in Windhoek/Namibia, in September 2013, the
Conference of the Parties (COP) decided to establish a Science-Policy
Interface (SPI) (decision 23/COP.11)
The goal of the SPI is to facilitate a two-way dialogue between scientists
and policy makers in order to ensure the delivery of policy-relevant
information, knowledge and advice on desertification/land degradation
and drought (DLDD)
The SPI’s mandate and scope of activities are designed to strengthen
the work of the scientific community working on DLDD, including the
UNCCD’s Committee on Science and Technology (CST)
What is the SPI?
Subject
Who are the members of the SPI?
Twenty scientists from different parts of the world

Subject
History of the SPI COP 11 - 2013 COP 9 - 2009 COP 8 - 2007 COP 10 - 2011
10-year Strategy
adopted Parties explored ways to
provide international and
interdisciplinary scientific
advice to the UNCCD
(assessment + e-survey)
Ad Hoc Working Group
(AGSA) tasked to make
recommendations on
suitable components for a
scenario to provide scientific
advice to the UNCCD
The country Parties
decide the CST should
establish the SPI
Recent developments:
- 4-6 February 2014: Terms of Reference (TOR) of the SPI agreed on at CST Bureau meeting
- May 2014: Composition of the SPI announced
Subject
Establish the approach to deliver each task assigned to it by the CST
Analyse, synthesize and translate relevant scientific findings and
recommendations from DLDD-related scientific conferences (SC)
(including upcoming UNCCD SCs), the roster of independent experts, as
well as from relevant stakeholders and networks into proposals to be
considered by the CST for the consideration of the COP
Interact with existing multiple scientific mechanisms, in particular the
Intergovernmental science-policy Platform on Biodiversity and Ecosystem
Services (IPBES), the Intergovernmental Panel on Climate Change (IPCC)
and the Intergovernmental Technical Panel on Soils (ITPS) and other new
and existing scientific networks and platforms
Assist the CST Bureau in organizing the UNCCD scientific conferences and
assessing their results
Mandate of the SPI (decision 23/COP.11)
Subject
Provide timely and policy-relevant scientific evidence on
Desertification, Land Degradation and Drought (DLDD) issues to the
UNCCD Committee on Science and Technology (CST).
Support CST´s cooperation with ongoing science-policy initiatives
that are relevant to the UNCCD and its parties.
Develop partnerships with relevant stakeholders to allow
preparedness and synergies in action to address DLDD to support
human well-being and sustainable development and achieving land
degradation neutrality (LDN).
Making that mandate operational:
Subject
The SPI has been tasked with exploring if the assertion
that SLM is an adaptation to climate change holds water,
and whether indicators for the state of the land can be
used for indicating the degree of adaptation to climate
change, and may be also an indication for biodiversity
change.
Therefore, the function of the SPI is not to carry out field,
experimental research on that, but assess the existing
science.
To paraphrase…
Subject
Scope of activities of the SPI (TOR)

Goal
Subject
SPI work programme up to COP 12 (Fall 2015)
Bring to the other Rio conventions the scientific evidence for the
contribution of sustainable land use and management to climate
change adaptation/mitigation and to safeguarding biodiversity and
ecosystem services
Increase the effectiveness of the UNCCD scientific conferences in
delivering policy relevant information, knowledge and
recommendations

UNCCD and its Parties
Subject
SPI Objective 1:
Bring to the other Rio conventions the scientific evidence for the
contribution of sustainable land use and management to climate
change adaptation/mitigation and to safeguarding biodiversity and
ecosystem services
Subject
The SPI endeavors to explore the scientific basis for the
contention that attending to land degradation is in and of
itself an adaptation to climate change and contributes to
the safeguarding of biodiversity and ecosystem services.
If we are worried about adapting to climate
change and/or the loss of biodiversity, why
concern ourselves with land degradation?
Subject
Defining “the future we want” for the planet we rely on, in
2012, world leaders at United Nations Conference on
Sustainable Development (Rio+20) resolved to achieve a
land-degradation neutral world (in paragraph 206).
The future we want
Subject
In the summer of 2014, the Open
Working Group of the General Assembly
on Sustainable Development Goals (SDG)
generated a proposal now being consider
by UN Secretary General.
Goal 15 reads:
Protect, restore and promote sustainable
use of terrestrial ecosystems, sustainably
manage forests, combat desertification,
and halt and reverse land degradation
and halt biodiversity loss.
Proposed Sustainable Development Goal 15
Subject
A UNCCD Intergovernmental Working Group (IWG) is tasked with
scientifically defining land degradation neutrality – their work is ongoing.
Achieving a state of land degradation neutrality involves both reducing
the rate of land degradation, and offsetting newly occurring degradation
by restoring the productivity and the provision of other ecosystem
services of currently degraded lands.

Land degradation neutrality
Subject
Biodiversity is the basis for healthy and productive
croplands and rangelands. Halving the loss and degradation
of ecosystems and restoring at least 15% of degraded
ecosystems by 2020, in line with the Aichi Biodiversity
Targets, and achieving land degradation neutrality, are
essential steps towards sustainable development, helping
us to produce more food, mitigate and adapt to climate
change and reduce our vulnerability to disasters.
— Dr. Braulio Ferreira de Souza Dias, Executive Secretary of
the UN Convention on Biological Diversity (CBD)
The policy imperative
Subject
Arictle 4 of the UN Framework Convention on Climate
Change (UNFCCC) text
1. All parties shall…
(e) Cooperate in preparing for adaptation to the impacts of
climate change; develop and elaborate appropriate and
integrated plans for coastal zone management, water
resources and agriculture, and for the protection and
rehabilitation of areas, particularly in Africa, affected by
drought and desertification, as well as floods;
The policy imperative
Subject
[In the face of environmental change]…more productive and
resilient agriculture requires transformations in the
management of natural resources (e.g., land, water, soil
nutrients, and genetic resources) and higher efficiency in
the use of these resources and inputs for production. — FAO
2010 “Climate-Smart” Agriculture Policies, Practices and
Financing for Food Security, Adaptation and Mitigation
The practice imperative
Subject
Research into desertification and climate change has the
potential to significantly enhance livelihoods of resident
people. It also has the potential to contribute to their
capacity for risk reduction, improved natural resources
management and adaptation to climatic and other changes
in multi-stressor systems.
— Seely et al. 2008 Global and Planetary Change
The research imperative
Subject
A more nuanced vision of sustainably managed drylands is needed:
one that reflects social and ecological realities and provides a
framework against which policies and investments can be assessed.
Such a vision should be based on the intersection between
sustainable land management and biodiversity conservation.
Gudka et al. 2014 Biodiversity
The [recent years] higher turnover rates of carbon pools in semi-arid
biomes are an increasingly important driver of global carbon cycle
inter-annual variability and that tropical rainforests may become
less relevant drivers in the future.
Poulter et al. 2014 Nature
Recent research supports pursuing a
synergistic approach:
Subject
While we aspire to achieve climate change mitigation (to
reduce exposure to risk), the reality on the ground is we
must also adapt to climate change impacts. Addressing
land degradation can help us increase adaptive capacity
and reduce sensitivity to climate change.

The SLM nexus
Many land-based practices, such as sustainable land
management (SLM), sustainable forest, integrated water
resources management, ecosystem-based resource
management, and community-based natural resource
management can help communities
and countries adapt to the impacts of
climate change and halt biodiversity loss.

changes in land productivity
changes to the resilience to climate change
changes in land use that reduce emissions
changes in relevant biodiversity components
Simple to draw, but not so simple to
implement
Synergies between the three Rio Conventions may seem
obvious – for example:
But the synergistic (across-Conventions) scoping, mapping,
prescribing, acting, monitoring & assessing, and enabling
(generating support) steps are less obvious.
What follows are just a few of the scientific
challenges this integrative approach presents

It is important to keep in mind that the risk of
desertification is a global problem…

Subject
Affected areas are not fixed in place and time, especially
under conditions of climate change.
Once this spatial domain is determined, the level of
degradation must be classified
Ideally this would involve a scheme that provides a
simple but effective link between mapping/classifying
degradation level and prescribing an appropriate action
…which brings up the question of “where”
Subject
Land under non-degrading use
Land at potential risk
(thus may need preventative
resilience-conferring action)
Would serve as a benchmark
Land under degrading use
Requiring degradation
mitigation (e.g., SLM)
Land already degraded
Requiring restoration efforts
One way to operationally slice up the land
degradation continuum
• Choosing what to measure to capture land degradation,
and through that, aspects of climate change adaptation
and the conservation of biodiversity is not easy!
• Many people (including scientists) propose measuring the
concern: land degradation
• Another approach is measuring what matters to people
and the environment: what the land produces
Advantages to a “measure what matters” approach:
simple, relevant, and sensitive to the concern at hand.
Subject
What to measure? Measure what matters!
• Changes in biological productivity of economic value
– Simple: routinely measured (e.g., crop yield)
– Relevant: to the 7.1 billion people who depend on the
biological products derived from the soil for their food,
provided by the 2.6 billion farmers whose livelihoods
depend on generating food from that soil
– Sensitive: A decline in crop yield is an indicator of land
degradation, it serves as an indicator of a key ecosystem
provisioning service, and can contribute to capturing trends
in above-ground carbon stocks
– Compatible: counterpart indicator, net primary productivity
(NPP), captures environmental value
Subject
An example:
• Trends in vegetation cover
– A decline in vegetation cover is an indicator of the
land’s regulating and cultural services, contributes to
understanding carbon stocks, and can be measured by
remote sensing.
• Soil degradation
– The chemical and physical degradation of the soil is an
indicator of the land’s supporting services and changes
in soil carbon.
NB: This approach separates out what matters (target),
what to measure (indicator), and
how to measure it (metric).
(Keeping these distinct also reduces unnecessary debate.)

…and then there are the apples and the oranges
Addressing a problem in one ecosystem type or
biome does not necessarily equal losses in another
(as the ecosystem services are different).
Therefore some provision for balancing within (rather
than across) ecosystem type is essential.
